Aside from the init script updates to create the PID the directory, I’ll posit that
the config files also needs to have the pid_file directive removed or commented out. /etc/mosquitto/mosquitto.conf # pid_file /run/mosquitto/mosquitto.pid The reason is that the start-stop-daemon used to start the daemon runs as root and creates it’s own PID file based on the init code. When the mosquitto daemon starts, it does a setuid to mosquitto, and if the pid_file directive is enabled with the same pid filename as the init script, the mosquitto daemon will fail over-writing the existing pid file owned by root. crichmon@testing:~$ ls -la /run/mosquitto/ total 4 drwxr-xr-x 2 root root 60 Apr 5 14:06 . drwxr-xr-x 18 root root 680 Apr 6 06:40 .. -rw-r--r-- 1 root root 5 Apr 5 14:06 mosquitto.pid Thx, Chris
